Swimming Pool Modelling

Dear bldg members,

I?m trying to execute a simulation approach on a swimming pool simulation
using EnergyPlus. I decided to write hoping you could give me some guidance
help on this kind of simulation approach since Energyplus does not have a
model for it.

The objective would be to simulate the pool environment, accounting for all
the heat transfer phenomenons, heat losses, etc., but more important the
evaporation losses which must be treated with dehumidification equipment.
The space must be heated and dehumidified using a standard dehumidifier

Defining the space and boundary conditions is not difficult using the
current geometry interfaces. At the end I would like to obtain the energy
consumption of HVAC equipment on treating the space loads (mainly
dehumidification and heating).

Can you give me some guidance help on what have you done in your approach on
EnergyPlus? Is there any other software or application which is capable of
simulating this kind of model?

Thanks in advance,

Hi Nuno,
I have not used Energyplus before. But I guess you would have to do a hand calculation to determine the evaporation rate and model it as a latent load. You could input that latent load as a plug load or even add to people latent load. I know that there is some ASHRAE journal/article which talks about how to calculate the evaporation rate in swimming pools. But unfortunately, I am not able to point you were to download that article. I am sure you can find it if you do some Google search. Hope this helps!
If you end up modeling in a different way, please let me know. I would be interested to know.

FYI...this is documented in the following report, and in the references that accompany the FCHART manual.


There was also substantial work done in the 1980s by Francis DeWinter at the Atlas Corporation, that included explicite algorithms for modeling the combined heat loss.
